蒸気圧縮式冷凍装置。 A compressor that compresses refrigerant vapor, a condenser that radiates heat and condenses and liquefies the high-temperature refrigerant vapor discharged from the compressor, an expansion means that rapidly expands the liquid refrigerant discharged from the condenser, and a refrigerant that passes through the expansion means. In a vapor compression type refrigeration system consisting of an evaporator that evaporates refrigerant and sends it out to the compressor, a bypass is provided which short-circuits the evaporator and has an electromagnetic on-off valve and an expansion means connected in series with each other. A passage is provided, and in the middle of the passage connecting the evaporator and compressor, starting from the evaporator side, there is a heater for adjusting the heating degree that heats the refrigerant in this passage, and a superheater that measures the degree of superheating of the refrigerant in this passage. A controller is provided which controls the energization of the superheat adjustment heater based on the signal from the superheat sensor and maintains the superheat degree of the refrigerant sent to the compressor at an appropriate value. Features of vapor compression refrigeration equipment.
